1700V 50mA Solid-State Relay
The NSI7258 is a single-channel solid-state relay (SSR), which is pin-compatible for popular photo MOSFET. The SSR turns ON with a minimum input current of 5.5mA. It can conduct 30mA current at ON state, with resistance less than 250Ω. The SSR turns off with an input voltage of 0.5V or less. It can withstand 1000V voltage at OFF state, with less than 1μA leakage current. The NSI7258 uses NOVOSENSE’s high reliability isolation technology. While the input circuit imitates the characters of LEDs, it has performance advantages compared to standard photo MOSFET, including better reliability and aging performance, higher working temperature, shorter turn-on and turn-off delay. As a result, the NSI7258 is suitable to replace photo MOSFET in high reliability system.
